PREPARATION OF THIS DOCUMENT
This document was prepared under the coordination of the Species Identification and Data Progrmme ofthe Marine Resources Service, Fishery Resources and Environment Division, Fisheries Department,Food and Agriculture Organization of the United Nations (FAO).
At a meeting of the Sub-Committee on Marine Environment and Ecosystems of the General Fisherycommission for the Mediterranean (GFCM) in February 2001 in Palma de Majorca, some membercountries concerned with the protection of sharks and other cartilaginous species suggested that a fieldguide for the identification of cartilaginous species be prepared. At its fourth session in June 2001 inAthens, the Scientific Advisory Committee (SAC) endorsed the suggestion and asked the COPEMEDProject GCP/REM/O57/SPA to support the preparation of the field guide.
This increasing recognition of the significance of sharks and batoid fishes as ecosystem healthindicators, as well as their particular importance in exploited ecosystems in the Mediterranean, havebeen key considerations to promote the preparation of this field guide.

Abstract
This volume presents a fully illustrated field guide for the identification of the sharks and raysmost relevant to the fisheries of the Mediterranean and Black Sea. An extensive literature reviewwas carried out for the preparation of this document. A total of 49 sharks, 34 batoids and1 chimaera are fully treated. The presence of 5 sharks and 2 batoids included in this field guide,need, however, to be confirmed. The guide includes sections on technical terms andmeasurements for sharks and batoids, and fully illustrated keys to those orders and families thatoccur in the region. Each species account includes: at least one annotated illustration of thespecies highlighting its relevant identification characters; basic information on nomenclature,synonyms and possible misidentifications; FAO common names; basic information on size,habitat and biology, distribution, importance to fisheries, and conservation and exploitationstatus. Colour plates for a large number of the species are included as well as two plates showingthe egg cases.

INTRODUCTION
After a long period of adaptation starting 450million years ago, since the Cretaceous (about
100 million years) the cartilaginous fish have notexperienced any further noticeable morphologicalor physiological changes. Today the group occupiesalmost all aquatic environments: rivers, lakes,estuaries, coastal lagoons, coastal waters, openseas and deep seas, extending as far as theAntarctic convergence. This may be facilitated bythe fact that sharks are mostly predators, and haveadapted to all sort of diets, some being scavengers.The few species that are plankton-feeders arecharacterized by large dimensions, whichdiscourages predation.
This guide provides a list and brief description ofthe species of sharks, batoid fishes and chimaerasliving in the Mediterranean and Black Sea. Whilefor some species there are no doubts regardingtheir presence in the area, for other rare species,their presence remains doubtful pending furtherinformation.
Commercial fishing samples constitute the mainsource of cartilaginous specimens, in particular, forrare species. Some species, once considered rare,may become common due to the increased use ofa particular gear or during fishing on new grounds.
Fishing may produce negative effects onbiodiversity: overexploitation of resources maydirectly or indirectly lead to the depletion of somespecies, especially those that do not have a goodresilience as regards to fishing disturbance, suchas the cartilaginous fish. In these cases it is quitefrequent to observe the disappearance, albeitlocally, of some species.
One major problem using official landing statisticsin any analysis is the difficulty to secure correctidentification of the species of cartilaginous fish, asthey are often grouped in collective codes. Apartfrom spotted dog sharks, thorn rays and a few otherspecies, caught as bycatch, a targeted fisheryaiming at catching cartilaginous species does notexist in the Mediterranean and Black Sea, and forthe time being, finning is not mentioned either. Intrawl fisheries discard may be a critical aspectespecially for juveniles of some species.
Physical and ChemicalCharacteristics of the Region
Geology and Physical Features
The Mediterranean Sea, Black Sea excluded,constitutes 0.81% (2.514 million km2) of the totalwater surface of the planet. Twenty-two differentcountries border its coastline. It extends from theStraits of Gibraltar to the Bosphorus for about4 000 km. The Mediterranean reaches its maximumdepth (5 121 m) in the Ionian Sea.
The birth of the Mediterranean was caused by thecollision of the African and European continentsabout 50–60 million years ago in the area presentlycalled Gibraltar. During the “Messinian regression”the Mediterranean basin became completelyclosed and the water level descended reaching itsminimum 6 million years ago. About 5.5 millionyears ago, communication through the Straits ofGibraltar opened again and Atlantic waters invadedthe Mediterranean basin. From then on theMediterranean Sea began a new life and assumedthe characteristics of a temperate sea.
The Mediterranean Sea can be divided into twomain basins: western and eastern separated by theSicily-Tunisia ridge. Within these basins, regionalseas may be defined, connected by channels andstraits (Fig. 1). The eastern basin is characterizedby a great oceanographic variability on the surfacewith temperatures of 16°C in winter and up to 29°Cin summer, as opposed to 12° and 23°C in thewestern basin and salinities of 39‰ to the east asopposed to 36‰ in the west.
Currently the Gibraltar threshold, with a maximumdepth of about 320 m and a distance of only 25 kmbetween the European and African continentalmasses, allows the passage of the Atlantic upperlayers with an average temperature of about 15°C.
The slow circulation of water masses, the rate ofexchange of Mediterranean waters and theconsequent poor water replacement, contributes inkeeping the temperature constant year round,particularly in deep waters.

The Black Sea occupies an area of about465 000 km2 and has a maximum depth of 2 245 m.The Marmara Sea connects the Black Sea with theMediterranean. Its salinity is low and does notexceed 22‰ throughout the whole water column,however surface waters may have lower values,down to 16–18‰. In winter the surfacetemperature decreases to 3–6°C and often, insome coastal areas, the water freezes, especiallyin the Azov Sea. At depths over 150 m thetemperature is practically constant, about 9°C. Thewaters of the southern coasts (Anatolia) showgreater average temperatures and are separatedby an isothermal front of 15°C. One of the maincharacteristics of this sea is the complete lack ofdissolved oxygen at depths over 150–200 m; fromthis depth to the bottom sulphurous concentrationis very high (Murray, 1991; Oguz, 1992, 1993).
Oceanographic Features
The distribution of marine organisms in theenvironment is clearly related to bottomcharacteristics, nutrients abundance and oceano-graphic conditions. These circumstances arenaturally linked to water masses large movements,both near the surface and in deep waters, and arealso influenced by meteorological conditions such aswind intensity, surface temperature and chlorophyleconcentration (Figs 2, 3 and 4).
The superficial layers of Atlantic waters flow inthrough the Straits of Gibraltar, progressing overthe entire surface of the Mediterranean basin area.These waters become warmer and progressivelysaltier due to evaporation and their great density asthey sink. Part of the general flow will return to theAtlantic as intermediate waters, while another partwill mix with deep waters. Heburn (1992) andGaribaldi and Caddy (1998) distinguish threedifferent ecological areas based on speciesdistribution. Three types of water thatfundamentally characterize the balance of thewhole Mediterranean can be suggested:
– The Modified Atlantic Water (MAW), which mainlyconstitutes the surface water (0–200 m) of thewhole area. It initially flows close to the NorthAfrican coasts, from Morocco to Cape Bon andthen splits into three main directions: the first oneconstitutes the cyclonic circuit of the BalearicIslands, the second moves towards the TyrrhenianSea (Astraldi et al., 1999) and the last one towardsthe Levantine Sea (Millot, 1999) (Fig. 5).
– The Levantine Intermediate Water (LIW)(200–1 000 m, mainly around 400 m depth) thatconstitutes the main component of the returning
flow towards the ocean. This water is mainlyproduced in the eastern basin (Lascarotes et al.,1992, 1993) and, to a lesser extent in the westernbasin contributing to the Tyrrhenian movement(Fig. 6).
– The Mediterranean Eastern and Western DeepWaters (MDW, Mediterranean Deep Water)(>1 000 m), that are produced respectively in theLiguro-Provençal area of the basin (Send andShott, 1992) and in the Southern Adriatic Sea(Fig. 7).
The general circulation in the Black Sea consists ofseveral sub-basin scale gyres. The anticycloniccoastal eddies appear to play a fundamental roleon the ultimate distribution of the Cold IntermediateWater (Oguz et al., 1992, 1993; Millot, 2005;Korataev et al., 2003) (Fig. 5).
In the area of entrance of the Atlantic waters (theAlboran Sea), there are important phenomenahaving repercussions on the entire Mediterraneanbasin (Fig. 8). These waters show an almostpermanent anticyclonic gyre in the west and a morevariable circuit in the east, (Allain, 1960; Lanoix,1974; Heburn and La Violette, 1990; Davies et al.,1993; Viudez et al., 1996). The main flow is fromSpain to the Algerian coast, commonly named “theAlmeria-Oran jet” (Prieur and Sournia, 1994). Afterabout 80–100 years the Mediterranean waters(LIW and MDW) return to the Atlantic Ocean withdifferent velocity running below the surface(Bryden and Kinder, 1991) (Fig. 9).
Biodiversity and BiogeographicalCharacteristics of the RegionThe current level of biodiversity of theMediterranean and Black Sea fauna was definedby the alternation of periods of glaciation andinterglaciation, which brought about dramaticchanges in climatic conditions. Also in recenttimes, biodiversity has been enriched both throughinternal speciation phenomena and throughspecies colonization from outside Mediterraneanareas (Golani et al., 2002).
Even though the Mediterranean and Black Seasrepresent less than 1% of the total area of worldseas, the fish biodiversity and absolute number ofspecies are relatively high. In fact, it is possible tofind about 6% of the entire world’s species in thisarea (Fredj et al., 1992) and probably the 84cartilaginous fish species found in the arearepresent about 8% of the total number of speciesof this group in the world.

Fig. 9 Inflow and outflow currents through the Strait of Gibraltar:a) transversal section, b) longitudinal section.
LIW spreads and mixes but remains a distinct water mass all the way to the Gibraltar Strait (Gascard and Richez,1985); LIW and MDW probably do not mix completely and flow out of Gibraltar Strait with different velocity (Millot,1999). The yearly average temperatures and salinity of LIW, MDW and MAW are illustrated respecitvely (Kinder andBryden, 1990; Millot, 1999; Robinson and Golnaraghi, 1994; Tintoré et al., 1988; Kinder and Parrilla, 1987). Therenewal of the waters of the entire Mediterranean basin is not known exactly; the eastern circulation is now known toconsist of a single cell encompassing both the Ionian and Levantine basins, with a turnover time extimated at about125 years. More research is needed to define the western cell (Roether and Schlitzer, 1991).
Two main features can be highlighted concerningMediterranean fish communities:
– Biodiversity decreases from west to east, probablydue to physical conditions such as the presence ofthreshold-strait or canal effects (Gibraltar,Sicly-Tunisia, Bosphorus, and Suez). The diversityin number of species shows the same negativeeastward gradient that has been found for nutrients(Murdoch and Onuf, 1972). Minimum biodiversityis present in the Adriatic and Black Sea (Fredj andMaurin, 1987; Garibaldi and Caddy, 1998).
– There is a meridionalization from the southern tothe northern coasts (Riera et al., 1995) and awarming trend in the deep waters of the westernMediterranean (Berthoux et al., 1990).
There are approximately 1 170 valid species ofcartilaginous fish in the world’s waters; about 50 ofthem are chimaeras, 650 batoids and 470 sharks.In the Mediterranean and Black Sea, 7 orders arerepresented by 23 families, 42 genera and a totalnumber of species of about 47 sharks, 34 batoidfishes and 1 chimaera. Endemism is low; up to fourspecies of rays could be considered indigenous.
In the Adriatic Sea, the presence of cartilaginousfish species is scarce especially in the northernpart. Besides its oceanographic characteristics thatmay limit biodiversity, this area was populatedmore recently than other parts of theMediterranean. This occurred after the sinking ofthe Dalmato-Garganic threshold, which was stillabove sea level in the Pleistocene. A total of 52species of cartilaginous fish have been recorded inthe Adriatic Sea. Only 10 species are widelydistributed. Some bathyal species of the groupinhabit exclusively the central and southern parts ofthis sea (Jardas, 1984).
In the Black Sea the number of cartilaginous fishspecies is less. The Pontic fauna is composed ofMediterranean species and most of the organismspresent are eurythermic and euryhaline. Twelvecartilaginous fish species are assumed to live in theBlack Sea (Tortonese, 1969; Bouchot, 1984; Rouxin FNAM, 1984; McEachran and Capapé, in FNAM,1984; Fredj and Maurin, 1987). Murat et al. (2002)consider only 8 elasmobranchs along the Turkeycoast of the Black Sea.
The Mediterranean Sea comprises severalsub-basins characterized by more or less widelydiverging oceanographic conditions and faunisticfeatures. Bearing this situation in mind, and alsoconsidering the proximity of the Mediterranea Seato the Atlantic Ocean, strictly speaking theMediterranean fauna can be defined as the faunaof a single, well-known, well-defined basin, and in a
wider sense the term also covers the forms existingin the adjacent part of the Atlantic, betweenPortugal and Mauritania including the Azores,Canary and Madeira islands (Tortonese, 1989).
For the last 5.5 million years, the Straits of Gibraltarhave never constituted a rigid boundary, and thereis, therefore a reciprocal influence between theAtlantic Ocean and the Mediterranean Sea. Infact,the classical statement of Ekman (1953) considersthe Atlantic-Mediterranean area as a singlefaunistic unit, and divides it into three areas:Lusitanic, Mauretanic and Mediterranean Region.
Even if considering only the Mediterranean basin, thedistribution of cartilaginous fish species is nothomogeneous. This phenomenon is often linked tothe typology of the sea bottoms or to the chemicaland physical characteristics of the differentsub-basins. Basically, the bathymetry delimits threedistinct ecological areas, which can be used tocategorize species distribution patterns and hencehabitat preference. Obviously, species could belongto more than one category or to all of them (Garibaldiand Caddy, 1998): 1) those living over the shelf(0–200 m); 2) demersal on the slope, oceanic andmesopelagic species within the water column overthe 200–1 000 m depth; and 3) oceanic, mesopelagicand bathypelagic species occupying waters over1 000 m depth.
The superficial Atlantic current, which comesthrough the Straits of Gibraltar, is of crucial impor-tance for Mediterranean Sea life as it facilitates theimmigration of oceanic species. In a very syntheticway we can state the following biodiversity consid-erations on several biogeographical areas of theMediterranean basin:
– The Alboran Sea is rich in Atlantic species.
– The northwestern area of the Mediterranean,including the Catalan, Ligurian and northTyrrhenian seas, is characterized by the presenceof Atlantic boreal elements.
– The central zone, that includes waters around theBalearic Islands, Corsica and Sardinia and thenorthern coasts of Sicily, shows specific Mediterra-nean or Atlantic-Mediterranean characteristics; manysubtropical species are found in this area.
– The Tunisian and Libyan coasts, characterized bythe presence of rare tropical Atlantic species, arethe southernmost areas and are closest tosubtropical in their characteristics.
– The eastern region, that includes the coasts ofEgypt, Israel, Lebanon and Syria, is inhabited bymany species coming from the Red Sea.

– The Adriatic Sea that does not reach greatdepths (50–60 m in average), apart from the“Pomo Pit” (south Adriatic Sea) where depthreaches about 1 200 m; the most abundantmarine organisms in this area are prevalentlyspecies of Atlantic-boreal origin.
– The Black Sea is characterized by species ofSarmatic origin.
The FisheryIn all the seas of the world, the cartilaginous fishspecies are exploited for their fins, skin, jaws ormeat (Vannuccini, 1999). Sometimes they aredirectly targeted by commercial and recreationalfisheries while in other cases they are incidentallycaught as bycatch. In many areas of the world adecline in cartilaginous fish species landings hasbeen observed while fishing effort has generallyincreased. This especially applies to fisheriestargeting shark fins. Moreover, most countriesreport shark statistics without distinction betweenspecies or, worse still, the species are not recordedat all. As a result, it is impossible to identify thespecies in multispecific fishery and hence estimateand monitor fishing mortality.
Because of their life history characteristics, sharksand rays are especially susceptible to over-exploitation and it is very difficult to restore depletedpopulations. Very often species have restricteddistribution, small population size, dependence onmating, spawning, nursery and breeding grounds orspecific habitats. Well- documented cases ofcollapsed shark fisheries have been reported(Musick et al., 2000). In such cases a suddencollapse of yields can occur and consequently thelocal extinction of a particular species.
No marine fish is yet known to have been driven tobiological extinction due to fishing (Musick, 1999) butregional stocks of some species can be consideredto have disappeared, such as Squatina sp. (Vacchiand Notarbartolo di Sciara, 2000). The assumptionthat marine fish are not vulnerable to extinctionbecause they live in open seas, where theirmovements are unlimited, is unfounded. Sharks alsoconstitute a bycatch in open sea fisheries targetinghighly migratory species such as tunas.
The fishing methods used to catch cartilaginousfish species in the Mediterranean are highly varied:the two most efficient gears for sharks are gillnetsand longlines, while a frequent method for catchingbatoids in general and some smaller sharks likesmoothhound, catsharks, etc. is the bottom trawl.This fishing gear is probably responsible for a large
amount of bycatch and discard of cartilaginous fishthroughout the world (Bonfil, 2002).
Bottom trawl fishing activity is commonlyperformed throughout the Mediterranean area. Thecartilaginous fish species most frequently caughtwith these gears are Galeus melastomus,Scyliorhinus canicula, Etmopterus spinax, Rajaclavata, Squalus acanthias (Bertrand et al., 2000;Relini et al., 2000; Baino et al., 2001; Serena et al.,2005). Some species such as the starry ray (Rajaasterias) are constantly captured as bycatch and inlarge amounts in several Italian fisheries,especially in the Tyrrhenian Sea. The fishing gearemployed is a modified beam trawl targeting sole(Minervini et al., 1985; Serena and Abella, 1999;Abella and Serena, 2005).
Even in the Adriatic Sea, accessory catches ofmany species of cartilaginous fish species arecarried out with set gears and the most frequentspecies caught are Squalus acanthias,Mustelus spp., Raja spp., Torpedo spp.,Scyliorhinus spp., Galeorhinus galeus, Alopiasvulpinus and juveniles of Carcharhinus plumbeus(Costantini et al., 2000).
Large individuals of Hexanchus griseus as well asthose of Galeus melastomus, Centrophorusgranulosus, etc. are captured with bottom longlinestargeting hake. The drifting longlines set near thesurface, targeting tuna and swordfish, also capturePrionace glauca, Pteroplatytrygon violacea,Alopias vulpinus, Isurus oxyrinchus, Lamna nasus,Sphyrna (Sphyrna) zygaena, Hexanchus griseus,Carcharhinus spp., Mobula mobular, etc. (Flemingand Papageorgiou, 1997; Kabasakal, 1998;Hemida, 1998; De Metrio et al., 2000; Garibaldiand Orsi Relini, 2000; Orsi Relini et al., 2000).
Driftnets are largely used to catch cartilaginous fishspecies, and in the recent past they wereextensively utilized throughout the Mediterranean.Fortunately nowadays their use is prohibited inEuropean countries. It is advisable that the use ofthis gear be prohibited, and this should beextended to all Mediterranean countries in order tofind a definitive solution to the problem. The mainspecies caught with driftnets are Prionace glauca,Alopias vulpinus, Isurus oxyrinchus, Lamna nasus,Carcharhinus spp., Cetorhinus maximus,Sphyrna spp., Mobula mobular, Pteroplatytrygonviolacea (De Metrio et al., 2000).
Occasionally, species such as Prionace glauca,Cetorhinus maximus, Sphyrna spp. and Mobulamobular are caught with purse seines (Notarbartolodi Sciara and Serena, 1988). In such cases the
8 Field Identification Guide to the Sharks and Rays of the Mediterranean and Black Sea
catches have to be considered incidental rather thanaccessory, the same applies to some artisanalfisheries (Serena et al., 1999a, b). No official practiceof “finning” has been reported in the MediterraneanSea so far, but mortality through discarding fromtrawls, gillnets, purse seines and longlines issignificant (De Metrio et al., 1984). However, in thepast the fishing activity with the greatest incidence incartilaginous fish species catches was tuna traps.Some years ago, these fishing structures were widelydistributed all around the Mediterranean area. Incountries such as Spain, France and Turkey, andparticularly along the Italian coasts, the use of thetuna trap was due to the presence of the prevailingmigration routes of tuna, directed towards not onlythe rich waters of the Liguro-Provençal basin but alsoin the Adriatic Sea (FAO, 1985). Between 1890 and1914, there were 37–54 tuna traps (Cushing, 1988) inItaly. Today only a few units are still present, mainlyconcentrated on the major Italian islands. Thelarge-sized cartilaginous fish species morecommonly present in catches were Alopias vulpinus,Cetorhinus maximus, Sphyrna mokarran, Prionaceglauca, Mobula mobular and sometimesCarcharodon carcharias (Boero and Carli; 1979,Vacchi et al., 2002).
Significant bycatch mainly constituted by Alopiasvulpinus and Prionace glauca is caught by fishingperformed with small swordfish-driftnets targetingswordfish, carried out mainly in the southern part ofthe Mediterranean by Italy, Malta, Morocco,Tunisia, and others. Very few and geographicallylocalized fishing activities can be considered,targeting species of this group in theMediterranean. Traditionally Hexanchus griseus iscaught with bottom longlines in the Ligurian Sea(Aldebert, 1997) and also along the southern Italiancoasts. In this area, drifting surface longlines,called “stese” are also utilized in spring for thecatch of large individuals of Prionace glauca.These are short lines with hooks that are set nearthe surface. In the northern Adriatic, gillnets areutilized to catch Mustelus mustelus, Musteluspunctulatus, Squalus acanthias, Scyliorhinusstellaris, Myliobatis aquila and Galeorhinusgaleus during winter and spring; and Prionaceglauca, Pteromylaeus bovinus and Alopiasvulpinus during summer (Costantini et al., 2000).
Important catches of Carcharhinidae species(Carcharhinus brachyurus, Carcharhinus brevipinna,Carcharhinus falciformis, Carcharhinus obscurus,Carcharhinus plumbeus and Carcharhinus altimus) arealso made by offshore pelagic longline fishery operatingfrom ports in the east of Algeria (Hemida and Labidi,2000). The recent FAO-COPEMED-MBRC report byLamboeuf (2000) analyses the artisanal fishery in Libyashowing some examples of fisheries targeting
cartilaginous fish such as Carcharhinidae, Lamnidae,Rhinobathos and Squatina squatina caught by fixedgillnet, bottom set and drifting longlines.
Finally, we cannot neglect the role of recreationalfishing that has recently grown in popularitycausing concern. Following the development thatoccurred in the United States and in Australia, thenumber of angler associations has also notablyincreased in the Mediterranean, mainly in thenorthern Adriatic (Bianchi et al., 1997) and in theTyrrhenian but also in other countries such asFrance and Spain. The targets of game fishing areessentially Alopias vulpinus, Prionace glauca andHexanchus griseus. However, juveniles composemost of the catch and, sometimes, they arerecently born individuals. Currently, there are nospecific laws or a suitable control aimed at theprotection of any cartilaginous fish. This may soonlead to a rarefaction of the populations of the twoabove-mentioned species as has already occurredin Cornwall, United Kingdom (Vas, 1995).
Cartilaginous fish catches in the 1970–2002 periodrepresent only 1.1% of the total landings inMediterranean ports (FAO, 2000a). The mostimportant landings of this group occurred in theIonian and Black seas each one with 30% of the totalMediterranean catches; Sardinian, Adriatic andBalearic waters show catches of 12%, 8% and 7%,respectively of the Mediterranean total.
The catches during the last 30 years (Fig. 10) showan increasing trend from 10 000 to 25 000 tonnesattained in 1985 and since then a regular decreaseto 15 000 tonnes to present (FAO, 2000b). This ismainly due to the Turkish and Italian catches ofsharks and rays in the Black and Ionian seas,respectively. Unfortunately it cannot be statedwhether these variations are real or if they aresimply due to changes in recording procedures (i.e.in some years at least part of them were reportedas sharks and in others generically as marinefishes).

Fishery ManagementThe life history strategy of cartilaginous fishspecies suggests the need for conservativemanagement of a balanced population and acompatible fishery activity. However, most sharkfisheries are completely unmonitored andunmanaged (Shotton, 1999). About 50% of theestimated global catch of cartilaginous fish speciesis gathered as bycatch and these are notmentioned in official fishery statistics (Stevenset al., 2000).
In general, the contribution of cartilaginous fish tothe market is low because of their scarce economicvalue. Consequently they are also a low priority forresearch and management if compared to bonyfishes, although recently, certain products such asshark fins have become important in the trade.
Cartilaginous fish resources management needsparticular attention, above all in order to maintainbiodiversity and ecosystem structures. Theinteractions between species in marineecosystems, as well as the impact of the removalof top predators on other marine organisms on thefunctionality of the whole ecosystem are poorlyunderstood. Basically, besides an adequateidentification guide, we need to know theabundance of each species, life historycharacteristics, fishing effort, catches, discards,etc. In the case of the Mediterranean, manyfisheries belonging to different countries are takingplace and the resources are often shared betweennations. This situation requires cooperativemanagement at the intergovernmental level and aprecautionary approach for their exploitation (FAO,1995a, 1995b, 1996).
Finally, for the successful management ofcartilaginous fish species we must simultaneouslyconsider biological and fishery information. Thechoice of suitable mathematical models for stockassessment of these resources is not easy and ithas to take into consideration the long life span andlate maturation of many sharks and rays.Therefore, the effects of changes in fishing effortand other management measures will be apparentonly many years later.
ConservationThe cartilaginous fish species belong to an ancient,conservative taxonomic group that was formerlyvery abundant in the world’s oceans. Despite theevolutionary success of the species which havesurvived until the present day, some are nowthreatened with extinction, regionally or globally,
often as a result of human activities. The mainreason for this is that a K-selected life-history traitscharacterize many species; they grow slowly,mature at a relatively late age, have only a fewyoung with low natural mortality rates, and theirpopulations increase very slowly (Hamlett, 1999,2005). As apex predators occupying the top of themarine food web, many cartilaginous fish speciesare also naturally rare compared with other fishspecies but have a vital role in maintaining thebalance of marine ecosystems. Their biologicalcharacters make them susceptible to populationdepletion as a result of anthropogenic activity,including unsustainable fisheries supplying localdemand or international trade, bycatch, habitatmodification and persecution (particularly ofspecies perceived as dangerous to man) (Myersand Worm, 2003).
The IUCN–World Conservation Union SpeciesSurvival Commission’s Shark Specialist Group iscurrently assessing global- and regional-extinctionrisks for all species of sharks and their relatives,including Mediterranean populations. This list isupdated annually as new information becomesavailable and may be consulted on www.redlist.org.The Red List has no legal standing, but is widelyused to monitor changes in the status ofbiodiversity and to set conservation andmanagement priorities. Regional networks ofexperts are involved in assessing and reassessingthe Red List status of species, drawing uponinformation collected by stock assessment andother research projects within the region (Fowleret al., 2005).
Recognition of the threatened status of sharks andtheir relatives has been recognized through theaddition of several species to national, regional andinternational species and fisheries conservationand management instruments. A number ofspecies of sharks and rays are listed in theAppendices of the Barcelona Convention for theprotection of the marine and coastal environmentof the Mediterranean (Protocol concerningSpecially Protected Areas and Biological Diversity)and the Bern Convention for the Conservation ofEuropean Wildlife and Natural Habitats, whichspecifically cover populations in theMediterranean. Other species are listed in theConvention on Migratory Species, the Conventionon International Trade in Endangered Species(CITES), and the UN Fish Stocks Agreement.Since some of these lists change fairly regularlyreaders are advised to consult the appropriateConvention web pages for the most up-to-dateinformation.
10 Field Identification Guide to the Sharks and Rays of the Mediterranean and Black Sea
It is important to note that the biologicalvulnerability of sharks1/, recognized in the FAOInternational Plan of Action for the Conservationand Management of Sharks (FAO IPOA-Sharks,1998) means that it is important to monitor thestatus of all species and to ensure that appropriatemanagement measures are introduced in order toguarantee the sustainable use of all shark stocks,not only those which are listed in the Conventionsor the IUCN Red List of Threatened Species.
Concerns over the sustainability of shark fisheriesled to the development and adoption in 1999 of theFAO IPOA-Sharks, 1998, elaborated within theframework of the Code of Conduct for ResponsibleFisheries (FAO, 2000). This voluntary plan urgesstates to carry out a regular assessment of thestatus of shark stocks subject to fishing, in order todetermine if there is a need for development of ashark plan, and to adopt a national plan of action(Shark-plan) for conservation and management ofshark stocks (if their vessels conduct directedfisheries for sharks or if their vessels regularlycatch sharks in non-directed fisheries). It alsorecognizes the importance of internationalcollaboration for the sustainable management oftransboundary, straddling, highly migratory andhigh seas shark stocks, including, whereappropriate, the development of subregional orregional shark plans.
The European Union considers that sharks are fishspecies whose conservation falls within the domainof the Common Fishery Policy, therefore theirmanagement should be addressed by measuresdictated by the EC for implementation within EUcountries. The European Plan of Action,announced at the FAO Committee on Fisheries(COFI) meeting held in Rome in February 2001, isstill to be released. Meanwhile, two meetings of thead hoc Elasmobranch’s Working Group of theScientific, Technical and Economic Committee forFisheries-Subgroup on review of stocks (STECF-SGRST) have been held (2002 and 2003) in orderto address elasmobranch fisheries with a view topreparing a Community Plan of Action asrequested by the FAO-IPOA Sharks. The draftItalian National Shark Action Plan recognizes theneed for regional cooperation in addition to nationalaction for Mediterranean shark species. This wasthe starting point for Italy’s active involvementwithin the relevant international and regionalorganizations, such as FAO and UNEP-MAP 2003.This stimulated the formulation of a MediterraneanAction Plan for the conservation and management
of cartilaginous fishes, proposed during meetingsof the GFCM-SAC working group on theenvironment in 2001 and 2002, and accepted bythe National Focal Points to the SPA Protocol in2001. The approved Action Plan was scheduled foradoption in November 2003. It stronglyrecommended that the representative parties granturgent legal protection status to a list of priorityspecies assessed as Critically Endangered or asEndangered by the IUCN at the Mediterraneanlevel and urges assessment of the extinction risk tospecies, such as hammerhead sharks andguitarfishes, for which data are lacking. Therepresentative parties are also asked to developmanagement programmes for sustainable fisheriesfor a number of commercially important species, toidentify and protect critical habitats and to developresearch, monitoring and training programmes.
Although legal instruments for the conservation ofsome cartilaginous-fish species in theMediterranean have been in place for over eightyears, implementation has not yet followed. Forexample, species listed under Appendix III of boththe Barcelona and the Bern Conventions, whichcall for the regulation of their exploitation, havecontinued to decline without any managementduring this period. There is now a critical need for aconcerted action and synergy of both fisheries andenvironmental agencies throughout the region toensure the conservation and sustainable use ofthis vulnerable group, and hence the maintenanceof the stability of the Mediterranean ecosystem.Such action should stem from the frameworks of allthose institutions whose mandate involvesenvironmental and fisheries policies within theMediterranean basin and the application of theecosystem approach and precautionary principle.It should also be mentioned that an Action Plan forthe Conservation of Cartilaginous Fishes in theMediterranean has been proposed (UNEP MAPRAC/SPA, 2003).
Codes for Conservation and Exploitation Status
With the aim of assigning status categoriesregarding the overall human utilization of sharks,the FAO (Castro et al., 1999) allocated sharksspecies into two main groups: “exploited” and “notexploited” species. The group “exploited species”is successively divided into five numericalcategories. These categories and criteria forinclusion are explained as follows. Unfortunatelybatoids are not yet considered in the FAO statusevaluation.
Introduction 11
1/ The term “shark” is used here in the sense of the Convention on International Trade in Endangered Species (CITES) and the FAOInternational Plan of Action for the Conservation and Management of Sharks (IPOA-SHARKS).
A. Not exploited species: species that are notcurrently targeted by fisheries and are not normallyfound as bycatch of any fisheries.
B. Exploited species: species that are directlyexploited by fisheries or caught as bycatch.
Category 1: exploited species that cannot beplaced in any of the subsequent categoriesbecause of lack of data.
Category 2: species pursued in directedfisheries and/or regularly found in bycatch,whose catches have not decreased historically,probably due to their high reproductive potential.
Category 3: species that are exploited bydirected fisheries or bycatch and, due to alimited reproductive potential and/or their lifehistory characteristics, are especially vulnerableto overfishing and/or are being fished in theirnursery areas.
Category 4: species that show substantialhistorical declines in catches and/or havebecome locally extinct.
Category 5: species that have become rarethroughout the ranges where they were formerlyabundant, based on historical records, catchstatistics or experts’ reports.
The conservation and exploited status of theMediterranean Chondrichthyans fish have beendiscussed in several meetings, UNEP-RAC/SPA inRome, December 2002 (UNEP 2003), STECF inBrussels, July 2003, (STECF 2003) andIUCN-SSG in San Marino, September 2003 (IUCN2003). Some other information proceeding fromelaborations of the data gathered during nationaland international surveys (GRUND, MEDITS,project N° 97/50 DG XIV/C1, etc.) (Relini et al.,2000; Bertrand et al., 2000; Megalofonou et al.,2000; Baino et al., 2001).
Some species as Chimaera monstrosa, Galeusmelastomus, Raja miraletus and Raja clavata, arereferred to as having a “stable biomass” in someareas from the exploitation point of view (Abellaand Serena, 2005; Serena et al., 2003).
12 Field Identification Guide to the Sharks and Rays of the Mediterranean and Black Sea
CLASSIFICATION AND SYSTEMATIC ARRANGEMENT
Considering that the purpose of this document is toprovide a simple user-friendly guide for speciesidentification, no reference will be found here todichotomy keys for single species. It is importantthat the classification used in this guide be defined,as available literature is not always in agreementwith this presentation. The classification of thisgroup is still under review as no consensus hasbeen found to reconcile different authors’ positions.
For more information and further specific details onthe taxonomy and biology of cartilaginous fishspecies, refer to Tortonese, 1956; Hureau andMonod 1979; Whitehead et al., 1984; Fischer et al.,1987; Fredj and Maurin, 1987; Compagno, 1988,2005; Nelson, 1994; Shirai, 1996; Mould, 1998. Theconsultation of FishBase http://www.fishbase.org(Froese and Pauly, 2000) proved very useful. Themost fundamental references are Compagno’scatalogues issued in 1984 and his recent revisionpartially issued in 2001.
This guide follows the systematic organizationproposed by Compagno (1999, 2001) and theclassification reflects a cladogram attempt where anew concept of cladistic classification is used. Forinstance, the batoids are raised to the order(Rajiformes) belonging to the superorder of theSqualomorphi, even if perhaps a more suitablename should be found to indicate both Rajiformesand Squaliformes. At the same time the sawsharksgroup is raised to the order Pristiophoriformes. Sothe batoids have been diversely allocated withrespect to the previous taxonomic organizations.However, even if this new phylogeneticclassification is considered valid, for practicalreasons sharks and batoids are describedseparately in the text.
Taking only modern sharks into consideration, wecan adopt the following, simplified classification(the orders with no representatives in theMediterranean Sea are indicated by an asterisk):
Class Chondrichthyes (cartilaginous fishes)
Subclass Holocephali (chimaeras)
Order Chimaeriformes (chimaera and silver sharks)
Subclass Elasmobranchii (sharks)
Superorder Squalomorphi (squalomorph sharks)
Order Hexanchiformes (cow and frilled sharks)
Order Squaliformes (dogfish sharks)
Order Squatiniformes (angel sharks)
Order Pristiophoriformes (sawsharks) *
Order Rajiformes (batoids)
Superorder Galeomorphi (galeomorph sharks)
Order Heterodontiformes (bullhead sharks) *
Order Lamniformes (mackerel sharks)
Order Orectolobiformes (carpet sharks) *
Order Carcharhiniformes (ground sharks)
The species inside the families and in the ordersare mentioned in alphabetical order according togenus. For both orders and families, somesummary descriptions with their most significantcharacteristics are included. The current status isdescribed for each single species on an individualsheet where, in addition to a drawing, scientificname and more recent synonyms and significantmisidentifications in some important cases, othersynthetic information is given, i.e. FAO commonnames, maximum size, habitat and biology,methods of capture and, when available,exploitation and conservation status. Arrows aresuperimposed on the drawings to indicate featuresthat help in species identification.
Introduction 13
When possible the type of spiral valve whichcharacterizes the intestine of cartilaginous fishes isshown. There are large variations in the anatomy ofthe spiral valve, three different types have beendescribed: columnar spiral with funnels pointingeither backward or forward; spiral ring valve andcylindrical (scroll) valve (Compagno, 1988;Hamlett, 1999).
Local names are not included considering the largenumber of names used in the variousMediterranean countries. Feeding behaviour isindicated only in some cases. Remarks areindicated for species whose taxonomic status orpresences are dubious.
For the purpose of this guide, a number of dubiousspecies have not been considered as valid for theMediterranean:
– Carcharhinus leucas (Valenciennes, 1841) is adoubtful species; it is neither recognized byCompagno nor in this guide.
– Carcharhinus longimanus (Poey, 1865) is adoubtful species; it is considered “probable” byCompagno but is not included in this guide.
– Rhinobatos halavi (Forsskål, 1775) was recordedby Tortonese (1951a) from the Egyptian part of theMediterranean Sea but Ben-Tuvia (1966) notedthat no specimens of this species were available toconfirm its presence in this sea.
– Torpedo alexandrinsis Mazhar, 1982 andTorpedo fuscomaculata Peters, 1855 are notconsidered a valid species. Torpedo alexandrinsisis known by only five syntypes mentioned in theoriginal paper from Alexandria (Egypt) (Séret,pers. comm.); therefore its taxonomic status isdoubtful. The second Torpedo species recordedonly once in Alexandria (Egypt) needs to beverified and is probably synonymous of Torpedo(Torpedo) marmorata (Séret, pers. comm.).
– The species Raja africana Capapé, 1977,previously defined as dubious by Compagno(1999), is now indicated as not a valid species(syntypes lost).
– Raja rondeleti Bougis, 1959 is probably based onan abnormal specimen of R. fullonica andconsidered as Leucoraja cfr. fullonica. Thetaxonomic status of four specimens from Frenchand Italian coasts is doubtful (Séret, pers. comm.).
How to use this guide
Readers are advised to follow these simple steps inorder to successfully identify any sharks, batoidsand chimaera found in the region. First, refer to thepicture key of shark-like and batoid fishes thenread carefully through the description of keycharacters listed under each order and family. Usethe illustrations of the families under each order orsuborder only as a secondary aid in making certainthat the right order or suborder has been found.Then proceed to narrow down the family of thespecimen using the illustration for each family andkey characters annotated in each illustration; makeuse of the size data included for each family. Oncethe family has been identified, move to thecorresponding pages where the species for thatfamily are illustrated. These illustrations and thekey characters indicated should allow properidentification for all sharks and batoids known forthe area.
In a few cases the considered area is wider thanthe Mediterranean basin; it refers to the CLOFNAMarea (Hureau and Monod, 1979): Mediterraneanand northeastern Atlantic between 30° and 80° ofLatitude north, -30° and +60° of Longitude, Azoresand Madeira Islands included (Whitehead et al.,1984).
Although Chimaera monstrosa (Linnaeus, 1758) isrepresented in the sharks cladogram as indicatedby Compagno, 2001, the species account isinserted at the end of the guide to follow thetaxonomic sense. Eventhough there is only onechimaera species in the Mediterranean Sea, theauthor thought it was important to illustrate thetechnical terms and description of this order.

This volume presents a fully illustrated field guide for the identification of the sharks and rays most relevant to the fisheries of the Mediterranean and Black Sea. An extensive
literature review was carried out for the preparation of this document. A total of 49 sharks, 34 batoids and 1 chimaera are fully treated. The guide includes sections on technical terms
and measurements for sharks and batoids, and fully illustrated keys to those orders and families that occur in the region. Each species account includes: at least one annotated
illustration of the species highlighting its relevant identification characters; basic information on nomenclature, synonyms and possible misidentifications; FAO common names; basic
information on size, habitat and biology, distribution, importance to fisheries, and conservation and exploitation status. Colour plates for a large number of the species are
included as well as two plates showing the egg cases.
